Method Detail

indexErrors

public static void indexErrors(CompilationErrorsIndex compilationErrorsIndex,
                               List<CompilationUnit> units)

Traverses a set of compilation units to record enough information to enable accurate and detailed compilation error cause traces.

logAndTranslateException

public static UnableToCompleteException logAndTranslateException(TreeLogger logger,
                                                                 Throwable e)

Used as a convenience to catch all exceptions thrown by the compiler. For instances of InternalCompilerException, extra diagnostics are printed.

Parameters:

logger - logger used to report errors to the console

e - the exception to analyze and log

Returns:

Always returns an instance of UnableToCompleteException so that the calling method can declare a more narrow 'throws UnableToCompleteException'

logErrorTrace

public static int logErrorTrace(TreeLogger logger,
                                TreeLogger.Type logLevel,
                                CompilerContext compilerContext,
                                List<CompilationUnit> units,
                                boolean hint)

Provides meaningful error messages and hints for types that failed to compile or are otherwise missing.

logErrorTrace

public static void logErrorTrace(TreeLogger logger,
                                 TreeLogger.Type logLevel,
                                 CompilerContext compilerContext,
                                 String typeSourceName,
                                 boolean hint)

Provides a meaning error message and hints for a type that failed to compile or is otherwise missing.

logWarnings

public static int logWarnings(TreeLogger logger,
                              TreeLogger.Type logLevelForWarnings,
                              List<CompilationUnit> units)

reportErrors

public static boolean reportErrors(TreeLogger logger,
                                   CompilationUnit unit,
                                   boolean suppressErrors)

Logs errors to the console.

Parameters:

logger - logger for reporting errors to the console

unit - Compilation unit that may have errors

suppressErrors - Controls he log level for logging errors. If false is passed, compilation errors are logged at TreeLogger.ERROR and warnings logged at TreeLogger.WARN. If true is passed, compilation errors are logged at TreeLogger.TRACE and TreeLogger.DEBUG.

Returns:

true if an error was logged.
